Make an active effort to think about each move and never weaken the King's pawnside structure (11...exd5 instead of 12...fxe5). Black lost pawns and pieces.
In tactical positions look at all checks and captures. There were a couple times where capturing with a different piece could have changed the game for Black.
Sometimes defensive moves must be played. Look for them & make them if no good aggressive alternative exists.
Watch out for forks!
